First of all, in the daily life, you can feeling the difference between wearing and not wearing a hearing aid. When wearing a hearing aid can communicate with people as normal, also can hear more than 80% of the voices of others, and be able to identify the general meaning of what others say, and which is better a lot than without wear a hearing aid, it means wear a hearing aids has a certain effect.
The second is to judge from a professional point of view, you can go to the hearing center to do a hearing test and speech recognition rate to compare the difference between wearing and not wearing.
The effectiveness of hearing aid use depends on the following factors:
The degree of hearing loss.
Hearing aids are more suitable for moderate hearing loss, and there are more choices of models with better effect; Hearing aids for mild hearing loss and severe hearing loss, the improvement is not as obvious as moderate hearing loss; very severe hearing loss is the worst, and the choice of models is also very limited.
The use of the environment
Just wear hearing aids, hearing aid effect has not reached the best, so during the period of adaptation to hearing aids should be in a relatively quiet place to listen, if all of a sudden to a relatively noisy place such as vegetable farms will make the wearer difficult to adapt to hearing aids.
The length of hearing loss and the early and late hearing intervention.
After the hearing loss is found, timely treatment or hearing intervention, optional hearing aids or other rehabilitation means, hearing loss and not timely intervention will lead to a gradual decline in their own speech resolution, so the earlier the intervention of patients, the better the effect of wearing hearing aids.
Hearing aid performance
At present, hearing aids on the market are mainly divided into analog hearing aids and digital hearing aids, and digital hearing aids have become the biggest demand due to the improvement of patients’ hearing requirements.
What are the advantages of digital hearing aids?
●Automatically adapts to the environment, effectively reduces noise and improves the clarity of speech.
●Mimics normal human cochlear function, enabling patients to improve their adaptability to different sound environments and to hear regardless of sound level without discomfort.
●Reproduce natural sounds to optimize the patient’s perception of his or her own voice and improve the naturalness, realism and comfort of the sound.
●Automatic elimination of feedback sound. Applying digital feedback suppression technology, so that the hearing aid will not have annoying feedback sound (whistling), which has an important role in improving the patient’s speech discrimination ability.
The difference between pre-speech deafness or post-speech deafness.
Patients with prelingual deafness rely on the clarity of their hearing aids to learn language because they have no language base for all speech. Therefore, there is a higher requirement for age. Patients with postlingual deafness have a language foundation and need hearing aids to raise the sound to achieve the purpose of hearing speech just fine. So the effect after hearing aid fitting will be significantly better than the former.
